MS Voyager of the Seas is the lead ship of the Voyager-class of cruise ships operated by Royal Caribbean International. Constructed in Turku, Finland, and launched on November 27, 1998, the ship was christened by Olympic gold medal-winning figure skater Katarina Witt on November 20, 1999.

As she departed on her maiden voyage the following day, November 21, 1999, Voyager of the Seas was the largest cruise ship in the world at the time. But she was overtaken the following year by her sister ship Explorer of the Seas.

In October and November 2014, Voyager of the Seas underwent refurbishment to receive "Royal Advantage" upgrades. These upgrades included the installation of an outdoor movie screen near the pool, replacing the inline skating track with a flowrider surf simulator, changing the Italian restaurant from Portofino to Giovanni's Table, and adding the Izumi Asian fusionrestaurant, Chops steakhouse, Diamond Club, and ship-wide Wifi.

As of 2016 Voyager of the Seas alternated between Australia and New Zealand itineraries out of Sydney during the Southern Hemisphere summer, and Asia itineraries out of Singapore and Hong Kong during the Northern Hemisphere summer.

In early 2017, Royal Caribbean announced that the Voyager of The Seas would be leaving Australia following the 2017-2018 season, and that it will be sailing in Singapore and China for a year-round season.
